Using python string formatting in a django template

Question

Is there an easy way to use python string formatting from within a django template? That is, I'd like to be able to do something like this in a template

{{ variable|%.3f }}

I know in this case, one can just use

{{ variable|floatformat:3 }}

But I'd really like to be able to generically use any python string format on a django variable. In my system it's inconvenient to have to deal with two different ways to format output (python vs django), so I'd like to standardize. I could write a custom template tag like

{% pyformat variable format="%.3f" %}

or maybe a custom template filter like

{{ variable|pyformat:"%.3f" }}

Do either of these already exist? Will the customer filter work with a string passed in like that?

Answer 1

{{ variable|stringformat:".3f" }}
